TO ALL WHOM '11 MA Y CONGERN:

Be it. known that I, BENJAMIN T. BABBITT, of the city, county, and State of New York, have invented a. new and improved -Process'of Preparing Coffee for use; and I dohereby' declare that the following is a full, clear, and exact description of the same. v

In the process of roasting coffee, as ordiparily.practised in preparing the some for use, much of the aroma thereof is unavoidably lost or dissipated, and furthermore, from the diificulty of maintaining a uniform heat, the quality or the coil'ec is otherwise fribuently impaired. The object of this invention is to obviate these objections to the common process of preparation, and to thisend it consists in boiling or cooking the green coffee in olive-oil, butter, or equivalent oleaginous or unctuous material, whereby not only is the escape or dis-- sipation of the aroma or volatile constituents of the cofl'ee wholly obviated, but the deterioration of the same; from want of uniformity in the temperature to which it is subjected, is also efi'ectually prevented, inasmuch as the oil or like material may be easily kept at any desired heat.

Toenable others to'understand the nature of my iiive'n'tionfI'will proceed to describe it.

In carrying out my invention, I take a cauldron or other vessel, of any suitable kind and capacity, and furnished with any appropriate appliances for heating to the required degree. In this cauldron I place a quant'ity of olive or other oil, or butter or animal fat, and raise the same to a temperature of, preferably, about 400 Fahrenheit, whereupon the green coffee is placed therein, and subjected to the cooking or boiling action of the heater] oil or material for a space of time, which, when the oil is at the temperature hereinbefore set forth, is found to be properly about five minutes. The coffee, being this boiled or prepared, is removed from the cauldron, and placed upon or within a suitable strainer, in order that the oil or unctuous matter may drain therefrom, and the cofi'eebe brought to a cool condition. It is preferred, however, that the coffee, in the first instance, be placed within a wire-gauze or otherstrainer, which, being placed bodily within the cauldron, allows the coffee to be boiled or prepared as just herein fully set forth, arid serves as a convenient means whereby the entire quantity of coffee may be removed from the cauldron at once, preparatory to the requisite draining of the oil or unctnous matter therefrom, as just mentioned.

The coffee being surrounded by' the hot oil or equivalentunctuous matter during its preparation, the escape of the aroma or volatile portion thcreoflis efl'ectually provided against; and inasmuch as the oil may be readily,

kept at the desired temperature during the whole operation, any injury to the quality of the coffee by excess ive heating is prevented. Furthermore, the hot oil being brought in immediate contact with'the entire surfaces of thc'cofi'ee-grainsor berries, the operation-of preparing the same as set forth, involves only a s mall portion of the time required in curryingout the ordinaryroasting-process, while little or-no additional expense is incurred, inasmuch as the oil, butter, or other like material, after having been once heated, may be used repeat- .edly'-in the preparation of different quantities or batches of coffee.

Whatl claim as my invention, and desire to secure by Letters Patent, is- The process of preparing cofiec for use by boiling or cooking the same in olive-oil, butter, or equivalent oleaginous or unetuous material, substantially as herein set forth.
